Microsoft Security Updates for March, 2017

After the last minute issue that resulted in the postponement of the February updates, security updates have been released for March.

Although this was to be the start of replacing security bulletins with the new Security Updates Guide, security bulletins were also published this month to provide extra time to prepare for the transition. The new guide includes the ability to view and search security vulnerability information in a single online database. The guide is described as a "portal" by the MSRC Team in Furthering our commitment to security updates.

Microsoft released a new cumulative update for PCs running the "Anniversary Update, Version 1607. KB4015438 replaces KB4013429 and is a quality improvement update and does not include any new features.

If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed.

There is one update each for Windows 10 version 1607 (Anniversary Update) and version 1511. The update includes quality improvements with no new operating system features introduced. The third update is for Windows 8.1, Windows Server 2012 R2, Windows 7 Service Pack 1 (SP1), and Windows Server 2008 R2 SP1.
